Clinical papers were not read directly; existing review summaries were checked. No new clinical-literature search was performed. Unverified does not mean that research is absent or that there is no effect.

## Assessment scope

- Population: The question concerns infants receiving vaccination. Hatfield concerns healthy term infants aged 2 and 4 months; Allen concerns ages 2 weeks to 18 months. Vaccine, injection counts, baseline details and detailed eligibility remain unverified by report.
- Ingredient, formulation and route: The intervention is clinician-administered oral sucrose. The key positive finding concerns 24% sucrose plus a pacifier; sucking, contact, holding and breastfeeding effects are not pooled as sucrose-only analgesia.
- Dose: Hatfield's 24% sucrose plus pacifier 2 minutes before vaccination is distinguished from Allen's 12% sucrose 2mL. Actual volumes, repetition, adherence and detailed amounts in other reports remain unverified. Research exposures are not converted into new use instructions.
- Comparator: Hatfield's sterile water, Allen's water and no intervention, and Gad's breastfeeding and control are distinguished. Detailed balance of amounts, contact, sucking, feeding and concurrent care remains unverified.
- Measured outcome: The selected question concerns behavioral pain and crying after vaccination. Hatfield's behavioral scores, Allen's crying and Gad's FLACC, crying time and heart rate are separated; pain-specific EEG and spinal reflexes during a different heel-lance procedure are not used as the same endpoints.
- Duration: Hatfield concerns the context from 2 minutes before vaccination to 5, 7 and 9 minutes afterward. Measurement times, duration and actual exposure in other reports remain separately unverified. Findings are not extended to repeated routine soothing or long-term effects.
- Questions outside this scope: Attributing composite behavioral signals to sucrose alone; Pooling water, no intervention, breastfeeding and different concentrations and ages as the same comparison; Extending vaccination behavioral calming to complete pain elimination or blocked neural nociception; Transferring physiological findings from separate heel lance into direct vaccination effects; Adding denominators across shared reports or creating new effects, intervals, optimal doses or repeated-use instructions

## Evidence and sources

### S01

Hatfield LA et al. 2008

[PubMed](https://pubmed.ncbi.nlm.nih.gov/18245406/)

Materials actually read: The complete stored parent Korean and English accounts and bibliography were read. External papers, registration, protocols, analysis plans and support disclosures are unread.  
Findings recorded in the summary: 100 infants randomized and 83 analyzed, 38 versus 45. Behavioral-pain scores with 24% sucrose plus a pacifier were lower at 5, 7 and 9 minutes; 7-minute means were 3.8 versus 4.8. The account's 17 analysis exclusions are also retained.  
Record level: These are stored composite-intervention findings. Original group allocation, exclusion reasons, time-specific variability, denominators and original CIs remain unverified. They are not promoted into sucrose-only contribution, complete nociceptive blockade or current independence certification.  
Independent replication: The behavioral-pain and crying question and the separate neural-response question share parent reports. Vaccination interventions, controls, ages and denominators are distinguished from separate heel lance. Report slots and family links are not added into new unique trial, participant or independent-replication counts; those totals remain unverified.

[PubMed](https://pubmed.ncbi.nlm.nih.gov/8603220/)

Materials actually read: The complete stored parent Korean and English accounts and bibliography were read. External papers, registration, protocols, analysis plans and support disclosures are unread.  
Findings recorded in the summary: 285 infants aged 2 weeks to 18 months. The original account reports that 12% sucrose 2mL and water both reduced crying versus no intervention at 2 weeks, without a sucrose-specific effect.  
Record level: These are stored findings specific to age, concentration and controls. They are not converted into effect 0 at every age or precise equivalence with water. Unverified funding and COI, and the pre-registration-era narrative, are not promoted into current searches or certification.  
Independent replication: The behavioral-pain and crying question and the separate neural-response question share parent reports. Vaccination interventions, controls, ages and denominators are distinguished from separate heel lance. Report slots and family links are not added into new unique trial, participant or independent-replication counts; those totals remain unverified.

Materials actually read: The complete stored parent Korean and English accounts and bibliography were read. External papers, registration, protocols, analysis plans and support disclosures are unread.  
Findings recorded in the summary: The stored account reports that breastfeeding was superior to sucrose and control for pain and crying in a trial of 120 infants, with P<.001.  
Record level: FLACC, crying time and heart rate are the original endpoint list. Individual heart-rate findings, group denominators, exact effects and CIs remain unverified. Breastfeeding superiority is not transferred to sucrose-only effects or reduced neural responses.  
Independent replication: The behavioral-pain and crying question and the separate neural-response question share parent reports. Vaccination interventions, controls, ages and denominators are distinguished from separate heel lance. Report slots and family links are not added into new unique trial, participant or independent-replication counts; those totals remain unverified.

[PubMed](https://pubmed.ncbi.nlm.nih.gov/20817247/)

Materials actually read: The complete stored parent Korean and English accounts and bibliography were read. External papers, registration, protocols, analysis plans and support disclosures are unread.  
Findings recorded in the summary: The parent account distinguishes the null prespecified pain-specific EEG primary endpoint during separate heel lance from behavioral-score differences and spinal reflexes. There is no separate entry in the stored evidence-summary list.  
Record level: This is stored context from another procedure and endpoint. Exact concentration, volume, timing, sample size and quantitative neural findings are unlinked. Vaccination doses, ages and denominators are not transferred to this trial, and it is not counted as direct replication of vaccination behavior.  
Independent replication: The behavioral-pain and crying question and the separate neural-response question share parent reports. Vaccination interventions, controls, ages and denominators are distinguished from separate heel lance. Report slots and family links are not added into new unique trial, participant or independent-replication counts; those totals remain unverified.

## Review criteria and methods

These are Chamgap's own application conditions, informed by the relevant sections of official methodological guidance. They do not constitute official assessment-tool certification or a new efficacy score.

- M03 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-03) · §3.1, §3.2.1–3.2.3, MECIR C5/C7/C13 · Clearly record the question, eligibility conditions and reasons for changes, and distinguish variations in interventions. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.
- M04 [Cochrane Handbook 6.5.1 (2025), chapter updated 2025-03](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-04) · §4.5, §4.6.1–4.6.3, MECIR C42 · Distinguish studies from reports and link them; do not omit a study solely because results are unreported. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.
- M08 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-08) · §8.1–8.2.3, Table 8.2.a · Define the outcome and effect of interest, then examine randomization, deviations, missing data, measurement and selective reporting. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.
- M15 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-15) · §15.2.4, §15.3.1–15.3.3 · Distinguish effect estimates, intervals, importance and applicability. Sample size alone does not determine precision. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.
- M19 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-19) · §19.1.2, §19.2.1–19.2.4 · Harm questions may require different designs, populations and follow-up from efficacy questions. Case reports do not establish incidence rates. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.

## What the statuses mean

- Partly verified: Partial information from the stored summary is linked; detailed originals and content review remain incomplete.
- Unverified: Required details cannot be established within the preserved scope. This does not establish absence of effects or studies, or safety.
- Review incomplete: Review of existing content remains incomplete.
- Met: This state is used only within the relevant conditions after material verification and content review. It was not automatically assigned in this work.
- Not reported: Unreported within material actually read. Unread external material is not relabeled as unreported.
- Inaccessible: This means actual access failure. External access was not attempted in this work, so this state was not assigned.
- Not applicable: Used only with an application exception and reason based on the question scope.
- Conflicting data: This requires actual comparison of materials; no new conflict judgment was made in this work.
- Insufficient evidence for the conditions: This indicates gaps in additional material for the selected conditions. Unread material as a whole is not converted into an efficacy grade.
